I picked up one of these panels recently. They're pretty nice. They have a good flexibility to them unlike goal zero folding panels. However, side-by-side to a goal zero nomad 7 plus it actually charges a little slower (goal zero is 7w and this EnerPlex is 6w). The difference is very little tho (about 1 minute longer per every 10% of battery).
The weight is pretty good at 294g (bare minimum).
